This invention relates to control apparatus for -air Apressure pumpisystems.

The invention relates Pto subject-matter which `'is somewhat similar to that shown in 15 my Patent No. 1,546,930, granted lJuly 21, 192,5, A,and "embodies improvements over the structureshown therein.

A" primary object ofy the invention is -to provide apparatus ofsimple andl staunch 10i construction which will automatically deliverwater from a Well or container to a desired point. Another object is to provide mechanism by which water lor other liquid maybe lifted in a plurality of stages to a mi? desired height.v @ther objects and advantages will appear as the specifica-tion proceeds.

but :preventsthe :flow of water from the tank when `compressed air is introduced thereinto. The tank is provided with a `water draw-oidl pipe 41v1 which vcommunicates with faucet C. Tank A is also connected with a compressed air line 12 which communicates `at its other end with a valve chamber 13. Pipe 411 come a niufnicates lwith lexpansion tank D through iFi-g. 6 is an enlarged plan view of a portionv line 14, and ywith the pump ychamber through pipe 15.

The pipe line 11 is provided at a point between pipe 15 and the tank A witha checkvalve 16 which is constructed so/as to prevent back Vflow of water. On the Vopposite side of pipe 15, there is 'located Iin-` pipe 11 a spring-urgedl valve 17 'which is set at apressure of from, say, three to ve pounds to prevent fthe flow of water toward the faucet v(.

Referring now to Figs. 1 to 6, inclusive, the pump chamber B maybe constructed incylinder forni and provided with a head 18 and a bottom 19. VAfreely movable piston I2O is mounted within chamber B and is formed preferably ofa pair of metal plates 21 and a pairllof cup-shaped leather disks 22 secured between the Aplates rv2O. Bolts or rivets 2-3 Ymay be-employed to secure the plates 21 and leather pieces 22 together;

The swing bar 25 is pivotally secured at-one end to a fixed post A26. At its other end, the swing fbar 25 has pivotal connections with a draw-bar ,27 which extends to ,and is connected to lever 34. At an intermediate point bar 27 is provided with a shoulder37. Above the shoulder 37, the bar .127 is reduced at 29.

tion "29 ,arey the tubular members 28, 39, 31

valves is provided with a box or casing which extends above the head. In the box above valve seat 40, apertures 42 are provided which allow the air within the pump cylinder to escape. A valve head is carried by a valve stem 43 which is reoiprocally guided in the housing above the valve seat. The lower end of the valve head is securedto a hinged lever 44. The lever 44 also carries a valve stem 45 upon which a valve head adapted to seat in valve seat 41 is carried.

In the illustration given, a valve box 46 is supported adjacent the cylinder head 18 and is provided with an exhaust valve seat 47 similar to valve seat 40 with which cylinder B is provided. Above the valve seat 47 is a casingiprovided with exhaust ports 48. Reciprocally guided in the casing is a valve 49 which is connected to a hinged lever 50. The

`valve box 46 is also provided with an air valve seat 51 which is similar to valve seat 41 on the cylinder head 18. A valve is supported by a valve stern 52 which is connected to the hinged lever 50. Above valve seat 51 is a box or closed casing. An air line 53 which communicates with a compressed air tank (not shown) leads to the valve seat 41 of cylinder B, and the valve seat 51 of valve box 46. An air line 12 leads from valve box 46 to the well tank A.

An extension 54 of the valve bar 39 beyond post 35 is provided with a yoke 55 adapted to engage a spool head 56 with which the stem of valve 49 is provided. The swinging of lever 39 will thus serve to raise and lower lvalve head 49. Likewise the valve stem 43 is provided at its top with a stop member 57 adapted to engage the yoke 58 of a pivot bar 59. The yoke 58, as shown more clearly in Fig. 5, embraces valve stem 43. The pivot bar 59 is preferably pivotally secured to the short post 60 which is supported upon the head 18. Y

To actuate the pivot bar 59, weight mechanism is employed. As shown more clearly inv Fig. 5, a weight 61 is suspended upon a shaft 62 which, in turn, is secured to a cross-piece 63. The cross-piece is provided at one end with a yoke 6'4 adapted to engage a guide member 65. At its other end, the cross-piece 63 is rigidly secured to a bar 66 which is reciprocally guided by a ytube 67, the latter being secured by a member 68 to the head 18 of the pump cylinder B. The weight 61 is housed within a cylinder 69 which is provided near its bottom with two perforations 70 and 71 through which means for holding weight 61 in suspension may extend.

Referring more particularly to Figs. 2 and 3, the rod 66 is connected at its lower end to a flexible member 72 which, in turn, is connected to one end of a rock lever 73. The lever 73 is pivotally supported at 74. At its other end. the rock lever 73 is connected to the long rod 75 which, in turn, is connected by means of a cross-piece 7 6 to the rod 33.

In order to secure quick action of the valves in seating and in opening, a bent rod 77 is connected to the bar 39 and near its lower end is provided with a cam 78. The cam is supported adjacent a pin 79 and is drawn into contact with, the pin by a horizontal spring 80.

Referring more particularly to Fig. 5, a latch member 81 is pivotally secured at 82 and carries at its lower end a pin 83 which is adapted to extend through opening 70 and to engage the bottom portion of weight 61. Connected to an intermediate portion of latch member 81 is a long pin 84 which extends across the path of thelever 39. lVhen rod 39 is raised, therefore, it will engage the pin 84 and release the latch from engagement with weight 61.

Referring to Fig. 4, la second latch member 85 is pivotally supported at the point 86 and carries in its bottom portion a pin 87 which is adapted to extend through opening 71 and to engage the bottom of weight 61. A spring-drawn rod 88 is connected to the lower portion of member 85 and tends to draw the latch member out of engagement with the weight. To hold the latch member in engagement with weight 61, a flexible diaphragm 89 carries a plunger 90 which bears against the member 85. The diaphragm 89 is supported within a chamber formed by casing 91 and the plunger 90 is guided within an opening provided by the casing. Communicating with the casing chamber on the side of the diaphragm opposite plunger is an air line 92 which leads from the eX- pansion tank D. The diaphragm 89, when the faucet C is closed, is normally held in the position shown in Fig. 4, the pressure of the air in the expansion tank D serving to press the diaphragm in a forward position.

In the operation of the apparatus, the operator opens faucet C. The moving parts are then in the position shown in Fig. 1. The opening of the faucet permits the air in expansion tank D to escape and thereby releases the pressure which has been urging 4diaphragm 89 toward a forward position.

The plunger 90 is then retracted and the lever 85 is drawn back by spring-rod 88, t0- gether with the pin 87. The weight 61, being thus released, falls against one end of the rock lever 58. The yoke 58 is drawn against the stop member 57 and raises the valve against the valve seat 40. At the same time the valve lever 44 raises the valve out of valve seat 41, thus permitting compressed air to flow into the pump cylinder above the piston 20. Piston 2O is forced by the air downwardly aud discharges the water contained in the cylinder through the pipe connection 15 and through the spring valve 17 to the faucet C. The check-valve 16 prevents Gil theiiowfof water :back tothe well. The piston near-the bottom of cylinder Bl strikes the rod 24 and causes lever 25 tosw'ing downwardly drawing with it the long rod 27,. To-

f gether with rod 27 is drawn the lever 34.

73 is forced in an upwardly direction drawing, by means of `theflexible connection 72, the rod 66 toward its raised position. Rod 66 raises with it thecross-piece 63 and the weight :61 suspended therefrom. As the weight is raised past the opening 70, the latch member 8l, by reason of the weight of thek longk arm 84, swingsy inwardly bringing the pin :83 `below the weight 6l. The weight is thus held in suspended position.

As the long rod 27 is drawn down by .the pressure of the piston 20 against rod 24, the lever 39 which is kheld between the members 30 and 3l, is also depressed and the extension 54 of lever 39 is raised. During rvthis `operation the member 33 is drawn downwardly against the force of spring38 and-meets member 3l, thereby depressing the lever 39. The

yokez of extension 54, being in engagement with the spool head 56 of the valve 49, raises valve 49 to close the exhaust ports. Lever 5() within the valve box 46 is also raised and the valve carried by rod 52is lifted out :of

engagement with the valve seat 5l.l 'Compressed air now passes through line 53 into valve box 46 and yout through line l2 to the tank -A within the well or other body of water. This air forces the water within tank A through line ll intothe pump cylinder B. The check-valve 16 permits the flow of water iin this direction, but the spring pressed valve l7,-which is set at, say, from three to live pounds, prevents the iiow of the water toward the faucet C. The inflow of ywater into the cylinder B raises the piston 20 tothe top of the cylinder where it lengages shaft 36.

As shaft 36 is raised by contact with piston 20, the swing lever`34 is raised and the collar 37 on rod 27 lifts member 23 into contact with member 30, against the force of spring '28, thereby raising bar 39. The extension 54 of swingbar 39 presses down the valve 49 outof engagement with valve seat 47. At the same time, the swing bar 50 draws rod 52 down to seat Lthe valve within valve seat 5l. The supply of compressed air is thus .cut off and the eXhaustports are opened. The

air within the valve chamber 46 and also with-k in the tank A in the well -is exhausted through ports 48. Upon :the removal of the compressed air from tank A, water iows Lthrough theicheck-valve l10 into tank A to fill it again.

As swing bari39 is raised, it engages pin84 and trips the latch member 8l. If the faucet C remains open, so that the latch member 85 is inoperative, the retraction of the pin 84 willpermitlathe :weight: 61'to fall striking the pivoted lever 59, and the ycycle of operation which I have `j ust described is repeated.

The rod 7 7 is retarded .in its upward and ydownward movements by the engagement of tinues to operate until piston 2.0.is in raised po` sition, the cylinder B beingsubstantially full., of water. In this position, the lever 39 `,holds the latch member 8l out of Contact withy the weight. However, the weight 61 is maintained in elevated position by the ylatch member 85 whichfis pushed forwardby plunger 90. Upon the closing of the faucet, the compressed ai-r trapped in vfthe expansiontank exerts ;a pressure von .the flexible diaphragm 89` whichforces plunger 90 toward ya forward position. If the faucet C is :,opened, the operation,which has been described, is repeated.

lt will be observed that the operationof the parts is automatic, kand that the only movement required of theV operator is that of opening and closing the faucet. The Vapparatus Y employed is sturdy andof simpleconstruction, the use of needle valves and other delicate parts Vbeing' avoided.

By employing a two-stagelift, the water may be discharged at the faucet with Lconsi derable pressure. While I have described an apparatus in which a two-stage lift is furnished, it is obvious that 'the' parts may. be multiplied to lift the water through a greater number of stages. Inthe i'inal stage the water may be discharged .substantially under the full pressure of the .compressed air tank.

lt will also be observed that with the form of apparatus illustrated,:a supply of water is carried `in the pump cylinder :and is immediately available upon turning the faucet. It is `not necessary for the operator to wait until water can be 'forced fromthe well 'to the faucet.

The foregoing detailed description has been given. for clearness of understanding only and( no unnecessary klimitations vshould be understood therefrom, but the appended claims should `Ybe construed Vas broadly vas permissible in view .of the prior art.
